The vCenter adapter is an embedded adapter for vCenter Operations Manager. The adapter collects metrics
from vCenter Server.

How the Adapter Creates Resources
The
vCenter adapter can create resources in vCenter Operations Manager by using auto-discovery and manual
discovery.
When you enable auto-discovery for a vCenter adapter instance, the adapter discovers and creates resources
in vCenter Operations Manager after it runs a main collection query.
You can use manual discovery to restrict the resources that the vCenter adapter creates in
vCenter Operations Manager. With manual discovery, the adapter sends a request to vCenter Server to return
all available resources and you select the resources to add.
Data that the Adapter Collects
During each collection cycle, the vCenter adapter retrieves metric values, events, and relationships from
vCenter Server.
For metric values, the adapter queries for up to five of the most recent 20-second samples from vCenter Server
and calculates the average. The adapter also adds several aggregate metrics, which it calculates based on those
values.
The vCenter adapter collects metrics for the following vCenter Server objects:

Datacenter

Cluster

Resource Pools
